Improvement in converting rotary into reciprocating motion

OF LOOUST VALLEY, NEW YORK, ASSIGNOR TOV OF SAME PLACE.

IMPROVEMENT IN CONVERTING ROTARY INTO RECIPROCATING MOTION.

Specification forming part of Letters Patent No.,0,90, dated July 20,1858.

To all whom z't may concern.-

Be itknown that I, J. J. VEEKS, of Locust Valley, in the county ofQueens and State of New York, have invented a new and useful MechanicalMovement Designed for Convert ing a Rotary into a Reciprocating Motion;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawing,making a-part of this specification, said drawing being a side sectionalelevation of my invention.

.Ihis'invention consists in forming an arm obliquely on a rotatingshaft, and having acollar iitted loosely on said arm, the collar havinga rod attached to itat right angles, and the lower end of the rod fittedloosely in an aperture in the slide or article to which a reciprocatingmovement is given from the shaft.

To enable those skilledu in the art to fully understand and constructniyinvention, I will proceed to describe it.

A represents' an upright, which is attached to a proper base, B, and Gis a bearing on the upper end of said upright. D is ashzift, which isfitted in the bearing @,and E is an arm, which is formed on one end ofshaft D, but obliquely with it, as shown clearly in the drawv ing. Onthe arm E a collar or hub, F, is placed loosely and secured thereon by awasher, G, and pin a. rIhe inner end of the collar or hub F bears'against a shoulder, b, the face of which is at right angles with thearm'. `To the collar orhub F a rod, H, is attached, and the lower end ofthis is tted loosely in a circular aperture, c, made in a slide 0r bar,I, which is fitted between proper guides, d.

From the above description of parts it will be seen that by rotating theshaft D the oblique arm E will so actuate the collar or hub By thisinvention an extremely simple and economical means is obtained forconverting a rotary into a reciproeatinginotion, and there is anotherimportant advantage besides simplicity, to wit: rlhe position oftheslide or bar I relatively with the shaft D is not arbitrary-n that is tosay, the slide or bar may be shifted or moved obliquely with the shaft Dwithout at all affecting the perfect operation of the device The devicewill prove highly valuable in those cases where a requisite space is notafforded for other means now employed for effecting the same result. Forinstance, in driving the reciprocating sickles of hart-*esters severalwheels and a crank, or a combination of levers and a cam, haveheretofore been` em ployedfor the purpose, and necessarily crowded intoa small space, and thereby generally working imperfectly, besides addinggreatly to the weight of the machine. By my imL provement thisdifficulty will be avoided.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is`

Forming the oblique arm E on the rotating shaft D, and placing thecollar or hub F, with rod H attached, on said arm, the lower end of therod H being fitted in the slide I, substantially as and for the purposeset forth.
